"National Rail" matching MCP servers:

Adds a responsible-AI safety layer to any agent by exposing RAIL Score's evaluation, agent-guardrail, and compliance capabilities as MCP tools, enabling content scoring, injection detection, tool call evaluation, and DPDP compliance checks.

Agent Security & Hallucination Gate (x402)

Policy-gated agent spend with signed receipts and rail-extract audit: a fail-closed gate issues a COSE receipt for every allowed payment, and the audit reconciles those receipts against a rail extract so a settlement with no receipt is named rather than assumed. It settles on a mock rail, holding no wallet and signing no transaction.

Enables MCP clients to connect to miyoushe and HoYoLAB accounts with QR login, encrypted credential storage, multi-account and game role discovery, daily notes for Star Rail, Genshin Impact, and Zenless Zone Zero, plus stamina alert checks with deduplication.

An MCP server that brings NIST National Vulnerability Database (NVD) intelligence directly into Claude, enabling CVE lookup, product search, and prioritized risk assessment via natural language.

PII sanitization layer for autonomous AI agent pipelines. Detects and redacts emails, phone numbers, national IDs, private keys, and financial data before text reaches LLMs. Supports EN, ES (LATAM), PT (BR/PT), DE, JA.

Enables AI agents to search, retrieve, and analyze vulnerability data from the NIST National Vulnerability Database through a comprehensive Model Context Protocol server.

Provides offline access to Spanish national security framework (ENS) measures, enabling querying of Annex II, applicability matrices, and audit checklists for compliance assessments.

A Model Context Protocol server that retrieves CVE information from the National Vulnerability Database, allowing AI models to access up-to-date vulnerability data.

A Model Context Protocol server implementation to query the NIST National Vulnerability Database (NVD) via its API.

Enables identity verification by checking name, address, and date of birth against national databases.

Enables AI to verify KeyHalve-sealed documents from any platform. Verifies status, ciphertext integrity, rail attestation, time lock, and issuer trust without requiring decryption keys.

Deterministic AST vulnerability remediation and formal verification for AI coding assistants using Microsoft Z3 SMT logic.

Enables real-time verification of Korean business registration status and KYB identity checks using official Korea National Tax Service data.

MCP server providing immutable audit logging, policy enforcement, and compliance reporting for AI agent workflows, enabling regulatory compliance and chain integrity verification.

Enables querying CVE vulnerability data from the NIST National Vulnerability Database, including CVE lookup, product/version search via CPE filters, CVSS severity scores, and recent high-severity disclosures.

MCP server for searching NIST's National Vulnerability Database, enabling retrieval of recent CVEs, keyword/CPE/CWE searches, and detailed CVE information.

Provides tamper-proof audit logging for AI agents using SHA-256 hash chains, integrity verification, and compliance reporting for the EU AI Act.

Search and audit CVEs by keyword, severity, CWE, CISA KEV status, and CPE via the NIST National Vulnerability Database.

Enables AI agents to read, send, and reply to GPG-encrypted email over IMAP/SMTP, manage a contact book with key provenance, and archive and search everything read. Key material and message bodies are kept out of the model's context window, with encryption enforced by default.
